摘　　要：在多年对太原盆地井灌区地下水开采量和降雨量监测的基础上,分析了井灌区54a降雨量的特征,利用典型井计算原理统计了井灌区的地下水开采量,论述了不同水平年地下水开采量的特征,最后通过回归分析法研究了井灌区地下水开采量与降雨量的关系.研究结果表明,年开采量与年降雨量关系显著,年开采量随年降雨量的减小而增大;年开采量与4、9月份降雨量相关性最为显著;通过年开采量、年降雨量与基准年的比值分析表明,开采量比值和降雨量比值呈线性关系.On the basis of observations of the ground water exploitation quantity and precipitation in a well irrigation area in Taiyuan basin for more than 50 years,we analyzed the characteristics of the rainfall of the past 54 a in the well irrigation area and calculated the groundwater exploitation quantity using the typical well′s counting principle.Based on the studying the features of the underground water exploitation quantity in different level years and regression analysis,we found that the relationship between exploitation quantity and precipitation was significant,and that the exploitation quantity per year increased with the decrease of the precipitation.According to the relationship between the exploitation quantity and the monthly rainfall distribution among the year,the correlations of the exploitation quantity with the monthly rainfall in April and September were more significant than in other months.Upon analysis of the ratios of both the exploitation quantity and rainfall of recorded years with those in base year of 2006,a linear relationship was found between the two mentioned ratios.
